Abstract

An internal combustion engine includes: a combustion chamber with a suction opening; an inlet valve for closing the suction opening; a fluid supply line with an open end; and a gaseous medium supply line with an open end. The open end of the fluid supply line is in close proximity to the suction opening. The gaseous medium supply line surrounds a portion of the fluid supply line in the vicinity of the open end of the fluid supply line. The open end of the gaseous medium supply line is in close proximity to the open end of the fluid supply line. And the open end of the gaseous medium supply line is directed toward the suction opening of the combustion chamber. In operation, fluid is supplied through the fluid supply line in such small quantities that the fluid is in an almost pressure-free condition at the open end of the fluid supply line. The fluid is atomized by supplying a gaseous medium through the gaseous medium supply line and past the open end of the fluid supply line at a pressure which is different than the pressure prevailing outside of the open end of the gaseous medium supply line.
